A train has no steering capabilities, the breaking distance isn't even close to a car. All one can hope is that the train manages to stop within two times the line of sight, if lucky.
A selfdriving car should be able to stop a lot faster than a train, and has instruments that is supposed to be able to see an obstacle even in bad light.
In Arizona it is the driver's responsibility to yield to all pedestrians on the same side of the road. She somehow crossed 3 and a half lanes of traffic without the Uber SDV ever perceiving her. Their fault.
Coming back to this, I was wrong about the details of Arizona law. They require pedestrians to yield to drivers outside of crosswalks, marked or unmarked.
However, I still think Uber violated 28-794.1 and .3.
Notwithstanding the provisions of this chapter every driver of a vehicle shall:
1. Exercise due care to avoid colliding with any pedestrian on any roadway.
2. Give warning by sounding the horn when necessary.
3. Exercise proper precaution on observing a child or a confused or incapacitated person on a roadway.
